Well, here's my Ginny Weasley cosplay. Used for Oktoberfest at my school, and also for Part One of the Seventh movie. This wig is the same one as my Kairi one, so if you need specifics go there and check it out.
If you need specifics about my costume, or could use some help with a Ginny cosplay of your own, feel free to email me at darlingravenclaw@gmail.com!
